0.0–100.0% 
If the simulating signal is less than the water-level 
threshold and keep in the state after the delay time 
set by P15.13, report A-tF and dormant. If the time 
is  not  reached,  the  signal  is  bigger  than  the 
water-level  threshold;  the  time  will  be  cleared 
automatically. When the signal time is shorter than 
the  water-level  threshold  time,  the  time  will  be 
counted again. 
0 is full-water and 1 is no water. 
0–10000s 
Time setting of full-water delay 
Wake-up delay 
when full-water   
0–10000s 
The delay time setting.   
During the full-water warning, if the detected 
water-level signal is higher than the threshold of 
P15.12, the delay counts, after the time set by 
P15.14, the warning is cleared. During the 
non-continuous application, the delay timing will 
clear automatically.   
0.0–100.0% 
0.0%: Invalid. If it is not 0.0%, when the signal is 
longer than P15.15, it will report tSF fault directly 
and stop.   
Operation time 
of water pump 
underload   
0.0–1000.0s 
Set the operation time of underload operation. 
Under the continuous underload operation, it will 
report A - LL if the operation time is reached.   
0.0%: Automatic detection
